Description

Technical Field

[0001] This utility model relates to the field of oat processing technology, and specifically discloses a device for separating cooked oat bran powder. Background Technology

[0002] Oats are annual herbaceous plants belonging to the Poaceae family and the Avena genus. They have relatively tough fibrous roots, erect, smooth, hairless culms that can reach up to 120 cm in height and have nodes, loose leaf sheaths, transparent membranous ligules, flat, slightly rough leaf blades, and spreading, pyramidal panicles containing small florets. The rachis of the spikelet is nearly hairless or sparsely covered with short hairs and is not easily broken off. The first lemma is hairless on the back, and the basal plate has only a few short hairs or is nearly hairless and awnless, or has only a relatively straight awn on the back. The second lemma is hairless and usually awnless.

[0003] Oats are a globally cultivated crop, and oat bran flour is made from ground oats. After processing, oat bran flour needs to be separated using a separator to remove the bran. However, existing oat bran flour separation equipment often leaves residual bran flour during the crushing and separation process, resulting in incomplete separation, resource waste, and the bran easily clogging the screen mesh, causing a rapid reduction in the effective screening area and requiring frequent shutdowns for manual cleaning, severely hindering continuous production. Therefore, a mature oat bran flour separation device is needed to solve this problem. Utility Model Content

[0004] This invention proposes a device for separating bran from cooked oat rice. By constructing a closed-loop circulating grinding and automatic back-blowing cleaning system, it efficiently completes the fine separation and collection of rice flour and bran from cooked oat rice.

[0005] This utility model is implemented as follows: a cooked oat bran powder separation device includes a support frame, a processing cylinder and a screw conveyor are embedded in the outer wall of the support frame, and a first connecting pipe is connected to the upper side between the processing cylinder and the screw conveyor.

[0006] It also includes a grinding mechanism for grinding oat rice, including a drive motor mounted on the upper end face of the processing cylinder, the output end of the drive motor extending into the interior of the processing cylinder and fixedly connected to a rotating shaft, a grinding seat fixedly connected to the inner wall of the processing cylinder, and a grinding table matching the grinding seat fixedly connected to the outer wall of the rotating shaft.

[0007] A screening mechanism for screening rice flour and bran includes a conical filter cylinder fixedly connected to the inner wall of a processing cylinder, the lower end of which is connected to a second connecting pipe, and the other end of the second connecting pipe extends to the outside of the processing cylinder and is connected to a screw conveyor.

[0008] A backflushing mechanism for cleaning the filter cartridge includes a fan installed on the lower end face of a support. The fan's outlet extends into the interior of the processing cartridge and is connected to an annular pipe fixedly connected to the inner wall of the processing cartridge. Multiple air nozzles are connected to the outer wall of the annular pipe. A filter box is provided on the upper end face of the support. A filter plate is retractably connected inside the filter box. An air inlet pipe located above the filter plate and extending into the interior of the processing cartridge is connected to the outer wall of the filter box.

[0009] As a preferred embodiment of the cooked oat bran powder separation device of this utility model, the outer wall of the rotating shaft is fixedly connected with a plurality of circumferentially distributed stirring plates.

[0010] As a preferred embodiment of the cooked oat bran powder separation device of this utility model, the outer wall of the rotating shaft is fixedly connected to two brush plates that abut against the inner wall of the filter cylinder via a connecting rod.

[0015] The beneficial effects of this utility model are:

[0016] 1. A closed-loop circulation system consisting of a grinding mechanism, a conical filter, a screw conveyor, and a controllable slag outlet is used to repeatedly return bran containing residual rice flour to the grinding zone for crushing and friction. This process removes as much rice flour as possible from the bran, significantly improving the final yield of rice flour and ensuring the purity of the discharged bran, thus maximizing resource utilization and reducing waste.

[0017] 2. By integrating the back-flushing mechanism with the negative pressure dust collection system, the bran clogging the filter cartridge can be effectively cleaned after the separation operation is completed. The dust raised during the cleaning process is contained inside the system and collected in the filter box. This not only avoids dust overflow and environmental pollution, but also realizes centralized material recovery, improves the working environment, keeps the screening channel unobstructed, and ensures the continuous and stable working efficiency of the equipment.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 A cooked oat bran powder separation device includes a support 1, a processing cylinder 2 and a screw conveyor 3 are embedded in the outer wall of the support 1, and a first connecting pipe 4 is connected between the upper side of the processing cylinder 2 and the screw conveyor 3.

[0026] It also includes a grinding mechanism for grinding oat rice, including a drive motor 6 installed on the upper end face of the processing cylinder 2, the output end of the drive motor 6 extending into the interior of the processing cylinder 2 and fixedly connected to a rotating shaft 7, a grinding seat 8 fixedly connected to the inner wall of the processing cylinder 2, and a grinding table 9 matching the grinding seat 8 fixedly connected to the outer wall of the rotating shaft 7.

[0027] The screening mechanism, used for screening rice flour and bran, includes a conical filter cylinder 10 fixedly connected to the inner wall of the processing cylinder 2. The lower end of the filter cylinder 10 is connected to a second connecting pipe 5, and the other end of the second connecting pipe 5 extends to the outside of the processing cylinder 2 and is connected to the screw conveyor 3.

[0028] A backflushing mechanism for cleaning the filter cartridge 10 includes a fan 13 mounted on the lower end face of the bracket 1. The air outlet of the fan 13 extends into the interior of the treatment cartridge 2 and is connected to an annular pipe 16 fixedly connected to the inner wall of the treatment cartridge 2. Multiple air nozzles 17 are connected to the outer wall of the annular pipe 16. A filter box 14 is provided on the upper end face of the bracket 1. A filter plate 18 is removably connected inside the filter box 14. An air inlet pipe 15 located above the filter plate 18 and extending into the interior of the treatment cartridge 2 is connected to the outer wall of the filter box 14.

[0029] In this embodiment: cooked oat rice is fed into the processing cylinder 2 through the feed inlet 19. The drive motor 6 is started to drive the rotating shaft 7 and the grinding table 9 to rotate, cooperating with the fixed grinding seat 8 to grind and crush the material, separating the rice flour and bran in the oat rice. The separated mixture falls into the conical filter cylinder 10 below for sieving. The fine millet flour that has met the separation requirements passes through the filter cylinder 10 and is discharged and collected from the discharge port 23; while the bran that fails to pass through the sieve, as well as some bran clumps still attached with rice flour, remain inside the filter cylinder 10. Under the action of gravity, these materials enter the screw conveyor 3 through the second connecting pipe 5 and are continuously sent back to the top of the processing cylinder 2 through the first connecting pipe 4, re-entering the grinding zone to perform gentle crushing and friction on the returned bran again, further peeling off the rice flour that is trapped or not completely separated in the bran. Through circulating grinding and sieving, the bran is processed until it is relatively pure. After separation, the blower 13 is started. The airflow generated by the blower 13 blows back through the nozzle 17 to the filter cylinder 10, blowing up the bran that is blocked on the inner wall of the filter cylinder 10. The blower 13 also creates negative pressure in the filter box 14, thereby drawing the bran blown up in the processing cylinder 2 into the filter box 14 through the air inlet pipe 15 and filtering the bran through the filter plate 18.

[0030] As a technical optimization of this utility model, a plurality of circumferentially distributed stirring plates 11 are fixedly connected to the outer wall of the rotating shaft 7.

[0031] In this embodiment: when the rotating shaft 7 rotates, it drives multiple stirring plates 11 to rotate, stirring the material in the filter cylinder 10, which facilitates the sieving of rice flour and bran.

[0032] As a technical optimization of this utility model, the outer wall of the rotating shaft 7 is fixedly connected by a connecting rod to two brush plates 12 that abut against the inner wall of the filter cylinder 10.

[0033] In this embodiment: when the rotating shaft 7 rotates, it drives the two brush plates 12 to rotate through the connecting rod, thereby cleaning the inner wall of the filter cartridge 10.

[0034] As a technical optimization of this utility model, the upper end face of the processing cylinder 2 is provided with a feed inlet 19, the lower end of the processing cylinder 2 is provided with a discharge outlet 23, and the outer wall of the second connecting pipe 5 is provided with a slag outlet 20.

[0035] In this embodiment: the feed inlet 19 facilitates feeding, the discharge outlet 23 facilitates discharging of rice flour, and the slag outlet 20 facilitates discharging of bran.

[0036] As a technical optimization of this utility model, a servo motor 21 is installed on the outer wall of the second connecting pipe 5, and the output end of the servo motor 21 extends into the interior of the second connecting pipe 5 and is fixedly connected to a baffle 22.

[0037] In this embodiment: the servo motor 21 is started, and the servo motor 21 drives the baffle 22 to rotate, thereby opening or closing the slag outlet 20.

[0038] As a technical optimization of this utility model, the outer wall of the filter box 14 is provided with a door.

[0039] In this embodiment, a door is provided on the outer wall of the filter box 14 to facilitate opening the door for cleaning the filter plate 18.

[0040] As a technical optimization of this utility model, a controller is provided on the outer wall of the processing cylinder 2, and the spiral elevator 3, drive motor 6, fan 13 and servo motor 21 are all electrically connected to the controller.

[0041] In this embodiment, the controller facilitates the normal operation of the spiral elevator 3, drive motor 6, fan 13, and servo motor 21.

[0042] The working principle and usage process of this utility model are as follows: Cooked oat rice is fed into the processing cylinder 2 through the inlet 19. The drive motor 6 is started, driving the rotating shaft 7 and grinding table 9 to rotate. These rotate in conjunction with the fixed grinding seat 8 to grind and crush the material, separating the rice flour from the bran. The separated mixture falls into the conical filter cylinder 10 below for sieving. The fine rice flour that has met the separation requirements passes through the filter cylinder 10 and is discharged and collected from the outlet 23; while the bran that fails to pass through the filter, as well as some bran clumps still attached with rice flour, remain inside the filter cylinder 10. At this time, the servo motor 21 controls the baffle 22 to close the slag outlet 20. Under the action of gravity, these materials enter the screw conveyor 3 through the second connecting pipe 5 and are continuously sent back to the top of the processing cylinder 2 through the first connecting pipe 4, re-entering the grinding zone. The returned bran undergoes gentle crushing and friction again, further peeling off the rice flour that is trapped or not completely separated from the bran. Through circulating grinding and sieving, the bran is processed until it is relatively pure. During this process, the baffle 22 can be rotated by the servo motor 21 to open the slag outlet 20 slightly and check whether there is any rice flour residue in the bran. If the rice flour in the bran is completely separated, the baffle 22 can be rotated by the servo motor 21 to fully open the slag outlet 20 and discharge the bran. After separation, the blower 13 is started. The airflow generated by the blower 13 blows back through the nozzle 17 to the filter cylinder 10, blowing up the bran that is blocked on the inner wall of the filter cylinder 10. The blower 13 also creates a negative pressure in the filter box 14, thereby drawing the bran blown up in the processing cylinder 2 into the filter box 14 through the air inlet pipe 15 and filtering it through the filter plate 18. Finally, the door on the outer wall of the filter box 14 is opened to clean the bran filtered on the filter plate 18.
